The search giant currently has three main offices in London with one in King's Cross, one on Tottenham Court Road, and another in Victoria. It also has a smaller startup space near Old Street known as Campus.

Over the next few years, Google is planning to make King's Cross, a neighbourhood in the north of Central London, its main base in the city, opening a number of new buildings in the area.

Here's a look at some of the properties that Google is planning in King's Cross and some that it already has in the area and across the rest of London.

The area behind King's Cross has been significantly redeveloped over the last few years and Google is moving into a number of new properties in the area.

Google announced plans to build a new £1 billion HQ on the 300m green plot of land in 2013.

Architects AHMM drew up these plans for Google's UK in September 2013.

At the time, The Guardian wrote: "On a long, thin sliver of land between the railway tracks in King's Cross, where rusting gasometers and soot-caked sheds once stood, a multi-storey pleasure palace will soon rise out of the ground. Complete with climbing wall, indoor football pitch and a rooftop swimming pool, this is not a new leisure centre for the people of Camden, but Google's spanking new £1bn London headquarters - designed to make going to work feel like an exciting day out."

As Google stalled on its main HQ, it snapped up this huge building over the road which had already been built.

Staff began moving into 6 Pancras Square in June and up to 2,800 Googlers are expected to be in the building by the end of 2016, including Android engineers and AI researchers at DeepMind.

It has been designed to be more subtle and stylish than some of Google's other buildings, which have Google's bold colours throughout.

In addition to 6 Pancras Square and the Thomas Heatherwick building, Google is also planning to move into this yet-to-be-built property at King's Cross. It is being built on a plot known simply as "S2".

Outside King's Cross, Google has offices in Tottenham Court Road and Victoria. It's understood that these offices will eventually be closed as Google expands in King's Cross.
